I'm doing a site for someone who would like a small random selection of products put on sale at some percentage discount and stay on sale for a period of time, say a day or a week.
Then they would go back to normal price and a different random selection of products would go on sale.
Through googling I've seen discount and other sale-related modules but was hoping there was something like this - ie a featured item or items that is randomly selected and discounted.
If there's nothing OOTB, a suggestion for which module(s) to use as a starting point would be great.
